- Fix build on 10.1: disable -fno-defer-pop flag which is not known by clang
Makefile says this flag is crucial for gcc to disable certain
optimization, but I assume clang doesn't have this optimization as
it doesn't support the flag. clang >= 3.6 handles unknown flags
with a mere warnings, so the modification is only needed for clang < 3.6

lang/moscow_ml: Really add stage support this time
Only files installed in the post-install target were being placed in
stage directory. All the files installed in the install target were
being put at ${PREFIX}, and this is most of them. Strangely, portsmon
never complained about this.
